12Section 5 - Operating Instructions
Operation of control buttons
Use and operation of your Rambo Bike
Press and hold the power button located on the left side of the handle bar to turn on your bike.
Your bike comes with 5 levels of power or pedal assist.
Levels 1-5 can be used with either thumb throttle or pedal assist.
Level 1 is 20% motor power, Level 2 is 40% motor power, Level 3 is 60% motor power,
Level 4 is 80% motor power, and Level 5 is 100% motor power.
Level 0 uses no motor power, it is used as a safety
feature or for pedaling the bike under the rider’s
own power with no assist.
For more information on your LCD display
review the manual in your owners packet.
13How to use Thumb Throttle
When riding your Rambo Bike, the thumb throttle can be used from a complete stop if you choose.
The rider must select the appropriate pedal assist level according to rider skill and terrain. Then by
pushing down on the throttle the motor will engage and the bike will begin to move forward. The
pedal assist level can be changed while the bike is in motion. As the power level from the motor is
increased, the bike will react with more speed and power. When coming to a stop, after the MPH has
reached 0.0, the rider will have 6 seconds to use the same pedal assist level to take off again on the bike.
After 6 seconds, the pedal assist level will return to 0. To use motor power again, press the + button
until the desired pedal assist level has been reached.
How to use Pedal Assist
When riding your Rambo Bike, the pedal assist can also be used from a complete stop if you choose.
The rider must select the appropriate pedal assist level according to rider skill and terrain. Then the
rider can begin to pedal, and after 1 or 2 revolutions on the pedals (depending on speed) the motor will
engage and assist the rider in propelling the bike. The pedal assist level can be changed while the bike is
in motion. As the power from the motor is increased the bike will react with more speed and power.
When coming to a stop, after the MPH has reached 0.0 the rider will have 6 seconds to use the same
pedal assist level to take off on the bike. After 6 seconds, the pedal assist level will return to 0. To use
motor power again, press the + button until the desired pedal assist level has been reached.
Added Features of your Bike
Brakes: Rambo uses E-bike specific brakes on all their bikes. This means that when the brakes are
applied the motor can not run. This allows for safe braking and stopping.
Shift Sensor: Rambo uses an electronic shifting sensor to kill the motor briefly while you are shifting
gears. This ensures a smooth shift and less wear and tear on your drivetrain.
Ergonomic handlebar controls: Rambo has configured the absolute best handlebar configuration for
e-bikes. This ensures all operations can be done with ease. Shifter, thumb throttle, brakes, etc.
14STANDARD LIMITED WARRANTY
Bicycle Lifespan
Rambo Bikes™ have an expected lifespan depending on the level of care and/or use. Misuse, neglect and abuse will significantly
reduce the expected lifespan of your bike. Some types of riding styles - competition, jumping, downhill racing, and extreme
conditions or climates - will all impact the lifespan of your bike and its components. These types of riding may cause premature
failure of your bike and its components. This warranty does not extend to any failures associated with this type of riding, or to
any Rambo products that have been subject to misuse, neglect, abuse, or improper storage, or if the product is modified or altered
in any way other than as directed by official Rambo Bike instructions. Always have your bike periodically inspected by a qualified
bicycle technician. These inspections are crucial for the safety of you and others around you as well as extending the lifespan of
your Rambo.
Limited Lifetime Frame Warranty
Rambo bike frames are warranted against factory defects for the lifetime of the original purchaser as long as they remain the
owner of the Rambo bike. This warranty is non-transferable. Your Rambo frame is warranted against premature failure caused by
faulty workmanship or materials, as determined by Rambo Bikes. Frames must be returned to Rambo Bikes at the owner’s
expense for determination of defect and/or replacement. If a frame replacement is found to be warranted by Rambo Bikes, a
comparable frame (depending on availability) will be issued to the original purchaser. Front forks and suspension forks do not
have a lifetime warranty!
Warranty
Beyond the lifetime frame warranty, Rambo Bikes warrants all bikes, enclosed hardware (where applicable) and accessories to be
free from defects in material and workmanship for a period of twelve months from the original date of purchase. Some
components on your Rambo bike such as brakes, tires, tubes, chains, grips, motors and cables are not warranted against normal
wear. If you find a product to be defective, contact Rambo at 952-283-0777. All components must be returned at the owner’s
expense for inspection. Product repairs and/or updates not covered by warranty will be provided at a set rate. At its sole
discretion, Rambo will determine whether the component will be covered under this warranty. This warranty is in lieu of all
other warranties expressed or implied. You may have certain legal rights that extend beyond this warranty in certain states.
Terms and Conditions of this Limited Warranty
This limited warranty does not cover installation, disassembly, adjustments of components, normal wear and tear,
damage caused by improperly installed parts or components, installation and use of aftermarket accessories or storage
fees. Any installation of a powerplant (motor electric or internal combustion) other than powerplants supplies directly by
Rambo Bikes immediately voids this warranty. Some parts and components may from time to time become obsolete or
discontinued. Rambo Bikes reserves the right to substitute any component at its sole discretion. This is the only warranty
provided or honored by Rambo Bikes, and no other warranty will be honored unless specifically provided for by law. No
implication of merchantability or fitness for a particular purpose has been made by Rambo Bikes.
